Mineral wool is prized for its fireplace resistance and seem insulation Qualities. It’s notably fitted to properties where by fireplace codes are stringent or the place sounds reduction is important, like industrial vegetation or hospitals.
In addition it performs effectively underneath substantial-temperature problems and supplies all-natural vapour permeability, aiding avoid trapped humidity.
five. Spray Polyurethane Foam (SPF)
SPF insulation generates a seamless, monolithic layer that adheres straight to the roof deck. it provides superb air sealing, humidity defense, and thermal resistance.
-
decreases air leakage and warmth transfer.
-
Acts as both insulation and waterproofing in one software.
nevertheless, it demands competent applicators and stringent climatic conditions in the course of installation, that may affect undertaking scheduling.
Flat Roof Insulation structure methods
helpful insulation isn’t nearly content range — it’s regarding how Just about every layer interacts inside the roofing assembly. Canadian professional roofs normally use just one of such a few layout programs:
one. common Roof process
-
Insulation is installed under the waterproof membrane.
-
The membrane is absolutely subjected to The weather, which often can lessen its lifespan Otherwise properly shielded.
-
suited to structures that prioritize insulation Charge-efficiency about rooftop accessibility.
two. Inverted Roof technique (shielded Membrane Roof or PMR)
-
The water-proof membrane lies beneath the insulation, preserving it from temperature fluctuations and UV exposure.
-
perfect for Canada’s Severe climates and for roofs that come with pavers, terraces, or mechanical walkways.
